Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

your emerald ecu can control water pump, you wont need any extra sensors as it will do it using coolant temp, its just a couple of extra wires and a relay,

but i wouldnt bother for 10 years now i've used EWP that run continuously after the cwp controller packed up

Well I've ordered an evalution-designs water swirl pot to run in the top hose, that will then allow the air/steam to be recirculated back to the header tank via the 8mm hose. As for the EWP, I'd much rather get it running with the standard pump and a thermostat, than run without a stat. If this cures the problem, then I will investigate electric pumps for a later date. I had sod all room for at the front of the engine as it is x-(

But the beauty of the EWP is that it can be mounted wherever you need it within reason.

Like I said, sod all room, and I'd rather get to the bottom of the underlying problem first. Not ruling one out just yet, I even ran a wire in the loom for an electric water pump, just in case 8-)

Yep, I agree, try and find the underlying problem seems like the right way to approach it.
Maybe the Duratec is demonstrating for being put in a Fester.......

I'm at Bruntingthorpe on Friday with the Fiesta, for a cover shoot for Fast Ford magazine. So I'll put the radiator back together, and hopefully the swirl pot will have arrived by then. To be on the safe side, I'll leave the thermostat out, and I'll see how it runs.

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

As you no doubt know Graham , the coolant system works better with a bit of "back pressure" in the water , so how about taking the centre out of a stat and just fitting the outer piece?

sounds like good advise

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

Looking at the thermostat whilst sat cross legged on the garage floor with bits of car all around me (like you do) theres no where on the stat to drill any holes in to. The stat sits very deep in the thermostat housing, and is sealed off with an O-ring. The actual area to drill in to would be impossible to get a 6mm drill in to. By all means, post me a pic of a modified Duratec stat, and I'll try to emulate the holes.

Also, on the end of the stat, there is a metal disk, that is pressed in to the inside of the cylinder head. As the stat opens, this disk moves with the stat, and opens a new channel inside the head. I'd rather leave it as is.

arh yes it has a by pass stat, when the stat opens it opens one port and shuts another off, best left alone

Re: Grahamb's Mk1 Fiesta XR2 Duratec HE Hillclimber

I discovered that one of the two rear engine steady brackets broke at Shelsley Walsh. But then I'd literally only tack welded the steering rack mounted bracket together, which is why it failed. I had only planned to get the car mapped, not drive it with it fitted, but I forgot I'd just bodged it. :P

The new one is far better, though it is still just a temp measure. The torque limiter needs to be a lot lower down, and ideally, mounted on the rear of the gearbox. I intend to do this properly, but it'll do for Friday.





There is a small section of tube inside the box section, to prevent it from crushing when the bracket is bolted to the steering rack mount.

No difference with the top swirl pot plumbed in.
Same as before, overheats on tickover, raise the revs and the temp drops, drive the car and the temps stabilise.
?????

Ran her up to about 110mph on the return straight, all seems to run OK. Bonnet bulged at the rear, but no harm done.

Fitted filters for the day, as following the photographers car, threw up tonnes of grit and stones off the Bruntingthorpe surface, and the engine would have been fooked if I hadn't.

Had a drag race against the 4x4 Fiesta Cosworth, Photographers 530D, my friends M3 (15yr old car with 320bhp) and my Subaru Legacy Diesel, and I came last but on my 2nd and 3rd laps wrung 120mph out the Legacy at the end of the 2mile straight, and it was struggling to reach that. Manufacturers claim of 126mph is wildly exagerrated.

Didn't use the fiesta in the thrash as she's still not fully mapped, and running with one driveshaft too long.

The white bag inside the car is a cover over the photographers flash unit.



This is how the engine is today with the swirl pot plumbed in (top of picture)



My car will be on the cover of Fast Ford in next months magazine.

Slightly off topic and out of date. found this whilst having a sort out of my files.
